default_scope for select option builds invalid SQL.

This query failed in my app due to the fact that you can't declare multiple columns in the "SELECT count" fragment:

SELECT count(id,title) AS count_id_title FROM resources INNER JOIN resources_tags ON resources.id = resources_tags.resource_id WHERE (((resources.approved = 1) AND (resources_tags.tag_id = 109 )) AND (resources_tags.tag_id = 109 )) )

The query was invoked by "m = Model.approved" in the controller and then calling "m.size" in the view.

This is declared in the model: default_scope :select => 'id,title' named_scope :approved, :conditions => { :approved => true }
